ABSTRACT
The impact of short term no-till cultivation on infiltration rate and dry aggregate stability in mararraban daware, Girei local government area, Adamawa state were evaluated to compare some soil properties as affected by some tillage operations. The no-till cultivation was started in June 2015 and in January 2017 measurements of soil infiltration rate, dry aggregate stability, pH (soil reaction), organic carbon, electrical conductivity (EC), and soil texture were made. Sixty (60) Samples were collected, 30 samples in the No-till site and 30 in the adjacent conventionally tilled sites at depth of 0-20cm and 20-50cm respectively. Samples were prepared and the standard laboratory technique was used for laboratory analysis. Two infiltration test per site were also carried out. Using dry sieving method, sieves at apertures of 2mm, 1.18mm, 600µm, 425µm, 300µm, 150µm and 75µm was used and the aggregate of each class was determined by weighing the various soils being retained at each sieve and the relationship between them on each site was examined. The results obtained shows that pH was near neutral on both sites, EC was normal, OC and OM were generally low in all the soils of the study area. MWD (mean weight diameter) was higher in the CT site than in NT site, infiltration test was faster on the CT site than NT.
